Abstract
The present invention provides a glove having both high softness and high air tightness. A glove of the present invention has a fiber-made base having a shape of a hand of a person and a coating formed on a surface of at least a portion of the base, where a burning treatment is applied to the base, air tightness of a portion of the glove which has been applied with the burning treatment is maintained even when pressure of 9 kPa or higher is imparted to inside of the base, and the fiber-made base is formed of filament yarns.
Claims
exact text as granted — not AI-modifiedThe invention claimed is:
1. A method of manufacturing a glove comprising:
a forming step of forming a base, only of filament yarn, having a shape of a hand of a person and having an inner portion for receiving the hand of the person;
providing a coating liquid having a viscosity in a range of 300 mPa·s or more to 1500 mPa·s or less;
a coating forming step of forming a coating on at least an outer surface of the base;
a burning treatment step of performing a burning treatment at least to an outer surface of the base, before the outer surface of the base is coated with the coating, wherein the burning treatment burns off loop-shaped projecting portions of the filament yarn to flatten a texture of the outer surface of the base; and
a cleaning treatment step of cleaning and drying the base, to clean and shrink the base, before the burning treatment step;
whereby even when a pressure of 9 kPa or higher is applied to the inner portion of the base of the glove, air tightness is maintained where the coating has been applied to the base of the glove.
2. The method according to claim 1 , wherein the cleaning treatment removes an oil component from the base.
3. The method according to claim 1 , wherein the coating is obtained by immersing at least the outer surface of the base in a coagulant and then immersing at least the outer surface of the base in the coating liquid.
4. The method according to claim 3 , wherein the coating liquid includes at least one material selected from the group consisting of a natural rubber, an acrylonitrile butadiene rubber, a chloroprene rubber, a polyvinyl chloride, an acrylic resin, a chlorosulfonated polyethylene, and a polyurethane resin.
5. The method according to claim 4 , wherein the base is immersed in the coating liquid a plurality of times.
6. The method according to claim 1 , wherein the filament yarn is at least one of a polyester yarn, a nylon yarn, a vinylonyarn, a vinylideneyarn, a polypropylene yarn, and a polyethylene yam.Cited by (0)
